Files saved for version 11 write the keys of their text document by name
(/DocumentResources, /FontSet, /StreamTag) and the kinds of its strikes
by their long names (/FrameStrike). The reader found no stories in them,
so their text objects were filled with the page's type in painting
order: type outside the artboards was lost, and type on them could land
in another text object.
The keys the reader uses now get their numbers from the dictionary they
sit in, from the root down, before the document is read. A run whose
style is written by name as a style's number takes that style. Files
saved for later versions that write a newer key by name among the
numbered ones (a font record's VersionString, a paragraph's
ParagraphDirection) have those keys read too.
Type on an open path can now start before the path's start: its start
is stored below 0, the span runs from there, and the characters whose
middle falls before the path's start are not drawn, as SVG 2 lays out
text on a path (https://www.w3.org/TR/SVG2/text.html#TextLayoutPath).
The text keeps every character, and the start bracket stays at the
path's start. Past the path's end, text that does not fit is overflow,
as for other type on a path. Type that starts on the path draws every
glyph as before.
- SVG import keeps a <textPath> start before an open path's start
(text-anchor end or middle, or a negative startOffset) instead of
starting the text at the path's start, which drew every character.
- SVG export writes it as a negative startOffset.
- PDF export writes only the characters drawn on the path.
- The legacy .ai and .ai editing data writers write the type from the
path's start with the type attributes warning.
- type.pathOptions takes a start below 0 for type on an open path; on a
closed path it is the path's start, as before. A flip starts the type
at its start bracket. Dragging the center bracket slides it from where
it starts, and no further before the path.
- A click at the path's start places the caret by the first drawn
character, and the caret in the hidden characters stands at the
path's start. The highlight of substituted fonts and glyphs leaves
them out.
- Release Type on a Path keeps the first drawn glyph where it was
drawn, with the hidden characters before it.
- The Touch Type tool shows no box for a hidden character, and
text.touchType returns an error for one. A character with a drawn
glyph is changed by that glyph.

Opening an .ai graph now sets placed_art from the art as read (main's d3789f2b0c), so the comparison in the graph round-trip tests leaves it out, as it already leaves out placed.
The test for a Calligraphic path followed by samples of the pen varied
the diameter, roundness and angle with the pen all at once. It would
still pass if the reader checked only one of the three settings, left
out Tilt, or tested the pen modes and the variations separately.
- Four new cases vary one setting with the pen and fix the other two:
the diameter with the pressure, the diameter with the tilt, the
roundness with the bearing and the angle with the rotation. Each
keeps the drawn look with its note.
- A new brushed case pairs a Random setting that varies with a pen
setting that varies by 0. The path comes in brushed.
Follow-up to #7367.
The check that pen samples mark only the object before them used an
unbrushed filled rectangle as the following object. A style with no
brush ignores the samples, so the check passed even when the samples
marked every later object. The following object is now an unsampled
path with the same pen-varying Calligraphic brush, and the test asserts
that it comes in as a path stroked with that brush.
- Outline Stroke on a graph's strokes, including Object > Expand with
Stroke on, adjusts the bounds the graph keeps, the same way
Create Outlines on its labels does. Before, the stroke outlines
changed the bounds of the art without type, and the next redraw
stretched the plot by the width the outlines added.
- A graph that keeps `placedArt` and has no art other than type left
is no longer measured on the bounds of all its art. A label edit on
such a graph moved and stretched the plot at the next redraw; the
plot now stays where it is.
- A redraw no longer measures a move or scale on art that has no width
or no height now, such as a graph left with one axis line. Before,
the plot collapsed to no width.
- A clipping group in a graph that holds type is measured on its clip
when the clip does not depend on type, so moving art outside the clip
does not change the bounds. Blends, envelopes and repeats are
measured whole, as they are drawn.
- The doc crate's helper is named `graph_art_without_type` and sits
with the file's other free functions.
- docs/mcp.md lists Outline Stroke and states that moving an outlined
label, a swatch, an axis or a tick mark on its own can move or scale
the plot, and that a graph left with only labels, or with art that
has no width or height, does not follow a move.
- Tests: a scale of the graph made before outlining a label, a move of
a graph opened from `.ai` after its label is restyled and moved,
Outline Stroke after a move, a graph left with only its labels or
with one line, and clipping groups holding type.
When a Type 2 CIDFont or a Type 42 descendant of a composite font has no FontMatrix, the
font a cshow procedure sees as current now takes the identity as its default, as glyph
measuring and drawing do, instead of the 1/1000 default of other fonts.
- A graph opened from a .ai file now saves `placedArt` too. Moving or
restyling one of its labels before the first redraw no longer moves or
stretches the plot.
- Type > Create Outlines on a graph's labels now adjusts the saved bounds,
so the outlines do not read as a move at the next redraw. A move of
the graph made before the outlining is still followed.
- A `placedArt` with no width or height falls back to the bounds of all
of the art, as a graph saved without it does.
- `art_bounds` moves to the doc crate so the .ai reader can use it.
- docs/mcp.md describes `placedArt`, `placed` and when a redraw follows
a move.
- Tests: a legend across the top, a legend after a right value axis and
legend labels of several lines keep the plot in place through label
size changes; moving a category label on its own; outlining labels
before and after a move; a flat `placedArt`; a label moved in an
opened .ai graph.
Both .ai writers now write a graph that the .ai reader reads back as the
same graph with its records, so a saved graph opens again live, with its
table, type, axes and settings: %_Gs, the Gb, Gy, Gd, Ga/GA, Gz, Gc and
GC records, the graph's group with each series' group followed by a Go
tag, and %_GS (the published .ai file format specification, section 17
and appendix A). The records are the ones the reader in
crates/eps/src/import/ai/read/graph.rs (#7311) reads, in the form it
reads them.
The shared encoder in crates/eps/src/ai_graph.rs decides first whether
the reader keeps the graph whole: a column, stacked column, line or area
graph with a legend, settings the records carry, a table of 1 to 10,000
categories and 1 to 256 series with finite values, labels of at most 255
bytes without control characters, and art the reader attaches the graph
to. Any other graph is written as its art, with the existing warning, as
is a graph whose art the editing writer's object limit cuts short.
Tick-mark counts of 0 are written as 1, the count the reader keeps for
both.
Bar, stacked bar, scatter, pie and radar graphs, stacked column and area
graphs whose series marks carry a stroke their legend swatch lacks, and
line graphs with markers are still written as their art, with the
warning.
Type that the editing copy writes as its outlines (mirrored type, type in
a clip or symbol, type the text document can't hold) put its Text Wrap
Options on the group of glyph outlines. The reader then wrapped area type
around the glyph shapes instead of the type's bounds, so the wrap region
changed when the file was opened.
The group now ends with an unpainted closed rectangle at the type's
geometric bounds, with the type's lock and hidden state, that carries the
wrap options; the group keeps the type's name and has no options of its
own. The `.ai` reader already reads an unpainted path with its own
options (`text_wrap` in crates/eps/src/import/ai/read/document.rs), and
wrap resolution descends into a group without options. The rectangle
counts toward the object limit; without room for it the options are left
out with the limit's warning. Type without finite bounds gets no
rectangle, as it had no wrap region before saving.
